RBDs floating on FLIP-Fluid issue Sept. 15, 2022, 4:27 a.m.
To be more specific this happens because Houdini doesn't have enough information to calculate the final buoyant force to defeat gravity.
If you increase sim resolution (reducing Particle Separation) you will get the proper result.
Another cheaper way is to only increase the collision resolution (reducing Collision Separation) portion of the sim itself.
You can find feedback force information under the impulse subsection of the feedback sub-data of each RBD object.
Hope it helps.

Converting smoke object to polygon soup? Aug. 15, 2022, 12:23 p.m.
Hello.
Just give the Isovalue option in VDB Convert a small positive number like 0.001.

Calculating eigen vectors for a given matrix with VEX Aug. 15, 2022, 6:42 a.m.

Thanks a lot, man!
I'm just curious to know why SideFX doesn't add the eigenvector function to VEX!
VEX have svddecomp (singular value decomposition). I posted an example of it here:
https://www.sidefx.com/forum/topic/84345/#post-364636 [www.sidefx.com]
This is one of the topics I plan to cover in Pragmatic VEX: Volume 2.
Thanks a lot, dear @animatrix.
I am in doubt if SVD decomposition can yield eigenvectors of a matrix, instead, it gives eigenvectors for matrix times transpose of the matrix!
